Abstract: A family of bidirectional fractional DC-DC converter for high voltage, high power battery energy storage system is proposed in this paper. The proposed converter has the benefits of low cost, high efficiency since it only processes part of the total converted power. One extra low voltage battery pack is needed; however, it can be from a different voltage rail or seamlessly

Over the past few decades, lithium-ion batteries (LIBs) have emerged as the dominant high-energy chemistry due to their uniquely high energy density while maintaining high power and cyclability at acceptable prices. However, issues with cost and safety remain, and their energy densities are becoming insufficient with the rapid trend towards electrification of the transport
The ratio between energy output and energy input of a battery is the energy efficiency. (Energy efficiency reflects the ratio between reversible energy, which relates to reversible redox reaction in electrochemical research,
Zn-air-based hybrid batteries (ZAHBs), integrating the advantages of a conventional ZAB with supplementary redox reactions, have emerged as a promising solution to address those challenges.
Longevity, energy conversion efficiency, and battery safety are just a few of the areas where temperature plays a major role [96]. The energy storage control system of an electric vehicle has to be able to handle high peak power during acceleration and deceleration if it is to effectively manage power and energy flow. There are typically two main approaches used

This innovative battery addresses the limitations of traditional lithium-ion batteries
For these renewable energy sources to provide a stable, consistent power supply, it is essential that the batteries they rely on can deliver a high level of energy efficiency relative to the energy used to charge them.

The ratio between energy output and energy input of a battery is the energy efficiency. (Energy efficiency reflects the ratio between reversible energy, which relates to reversible redox reaction in electrochemical research, and the total battery energy. Most batteries have <∼95% energy efficiency in one charge/discharge cycle.
The applications of lithium-ion batteries (LIBs) have been widespread including electric vehicles (EVs) and hybridelectric vehicles (HEVs) because of their lucrative characteristics such as high energy density, long cycle life, environmental friendliness, high power density, low self-discharge, and the absence of memory effect [[1], [2], [3]].
